Abstract: 770,178. Treating liquids electrolytically. CARRIER ENGINEERING CO., Ltd., and CRAVEN, J. P. March 18, 1955 [Feb. 26, 1954], No. 5801/54. Class 41. [Also in Group XL (b)] A method of reconcentrating diluted mixtures, e.g. glaze, consisting of powder in a liquid, comprises placing the mixture in a tank 1 and creating in the tank an electric field which causes negatively charged particles of the mixture to move towards the bottom of the tank. An anode 2 overlies the base of the tank 1 and is connected through an insulated lead pipe 3 to a D.C. source, the cathode 5 being dish-shaped and floating on the mixture, a central hole 7 therein leading by a funnel 8 to a tube 10 connected to a suction device for removing clear water. The suction device may be automatically controlled by a photo-electric cell 13 separated by a transparent part 12 of the tube 10 from a light 14, to cut off the suction device if clouded liquid enters the tube 12 from the tank 1. Alternatively, the cell 13 may control a valve in a suction pipe leading from the tube 10.

Title: Improvements in electro-magnetic separators
IPC: B03C1/14

Abstract: 349,550. Electromagnetic separators. WINDLEY, F. W., Corner House, Broomfield Road, and WINDLEY, A. E., Lorraine, Upper Moulsham Street, both in Chelmsford, Essex. Feb. 22, 1930, No. 5925. [Class 72.] An electromagnetic separator comprises a vertical spindle, driven by any suitable means, carrying at its upper end a horizontal circular magnetic plate, the top face of which is split up to form a plurality of concentric or approximately concentric north and south poles. A spindle 4 mounted in bearings 5, 6, and rotated by belt drive 7 carries a horizontal magnetic plate 1 with a domed centre 2 which receives the material to be treated from a hopper 3 mounted above and coaxially with the plate. The plate 1 is formed in two parts, a thick part 19 containing an annular magnetizing coil 21 and a cover-plate in which are concentric grooves 16 filled with non-magnetic material. The coil 21 receives current from brush rings 11, 12 coacting with brushes 13, 14 mounted on a stationary casing 15 and connected to the current supply. The spindle &c. is enclosed in a casing 9 and the separator is contained in a vessel 10. The surface of the plate may be flat, convex or concave, the non-magnetic grooves may be in the form of a spiral and the plate may be stepped, Fig. 5, to facilitate the retention of the magnetic material. The non-magnetic material is thrown by centrifugal force into the vessel 10 which may be lifted to remove the material. The magnetic material may be removed from the surface of the plate by cutting off the current after a momentary reversal to demagnetize the plate, the material being then thrown into the vessel 10.

[Also in Division B8] In a process and apparatus for making a lean suspension of a constant proportion of a powder in a gas, the gas is fed into the mass 2 of the powder with velocity sufficient to break down agglomerations and fluidize it. A proportion of the suspension thus formed passes into the outlet duct 10, 9 while the remainder passes through the filter 6 where the powder is trapped and returned to the mass; the filtered gas is added to the suspension in the outlet duct 9 through the slots 11. The leanness of the suspension is controlled by the ratio of the area of the filter 6 to the mouth 10 of the outlet duct, and by bleeding off part of the filtered gas at 12. The upper portion of the chamber is of reduced diameter to increase turbulence.

Abstract: 349,576. Wireless receiving apparatus. GRAMOPHONE CO., Ltd., Hayes, Middlesex, and COOPER, A. H., Appledore, Syke Ings, Iver, Buckinghamshire. Feb. 26, 1930, No. 6434. [Class 40 (v).] A switching system for a wireless receiver comprises a quick-action switch and a plurality of switches of another type, and operation of the controlling member causes the switches to operate in succession, the quick-action switch remaining at the same setting during the operation of all the other switches. The invention is described w:.th reference to a quick-action main switch and a rotarv four-position wave-length selector switch. In the arrangement shown in Fig. 1, a pin 4 on a disc 3 carried by the spindle of a selector switch, engages a slot in an operating lever 2 of a quick-action switch 1. Thus on rotating the disc 3 to move the pin 4 from position A to position B, the switch 1 is closed. The selector switch can then be moved to position C, D, a stop 5 preventing further movement. When the selector switch is returned to position A after passing through the intermediate positions it opens the switch 1. Modifications are shown in which the selector switch can be rotated indefinitely in either direction and is provided with a system of levers for the operation of the quick-action switch. In a further modification, Fig. 7, the quickaction switch is operated by a disc cam 51 on the spindle 50 of the selector switch.

Title: Improvements in or relating to the purification of sugar esters
IPC: C07H13/06
Filed: 1961-02-23
Abstract: A sugar ester of an aliphatic carboxylic acid containing from 6 to 30 carbon atoms is purified by subjecting a solution, suspension or emulsion of the sugar ester in water to dialysis with water or a weakly acid aqueous solution.  After the production of the ester in known manner, the solvent is removed by distillation and the product is introduced as a solution, emulsion or suspension in water, having a concentration between 1 and 50% by weight, into a dialysing apparatus and dialysed with water or acid, e.g. N/1000 or N/100 acid. A similar effect is obtained by adding acid to the mixture of sugar ester and water before dialysis with water.  After dialysis with, or in the presence of, acid, a dialysis with water is desirable.  Animal or synthetic membranes, e.g. clay, natural gut, naturine gut, synthetic gut, parchment of "Cellophane" (Registered Trade Mark) are suitable as dialysing membranes.  Dialysis times are generally between 2 to 10 days if the surrounding medium is changed every 12 hours. Dialysis can be effected at temperatures between 0 DEG  and 100 DEG C., preferably between 30 DEG  and 60 DEG C.  The sugar ester after production may be re-purified by distilling off the solvent, taking up the ester in water to form an aqueous solution, emulsion or suspension, precipitating the ester with an electrolyte, such as an acid, e.g. hydrochloric, sulphuric, phosphoric, or organic acids, or common salt, and separating the ester by filtration, centrifuging or agitation.  The prepurified ester may then be dialysed as above. Examples of sugar esters which can be purified are sucrose monostearate, distearate, monopalmitate, dipalmitate or oleate, glucose ureide-stearate, N-hydroxyethyl-glucosylamino stearate, isopropylidene-glucose-stearate, a -methyl-glucosido-oleate, glucose-stearate, a -methyl-galactosidostearate and galactosidostearate.
